Application: kontact (4.4.9)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-12-server x86_64
Distribution: Ubuntu natty (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

Change sidebar options from Icons & Text to Icons Only or from Icons Only to Icons & Text, then close kontact -> kontact crashes.

This may be related to Bug 250138?

The crash can be reproduced every time.
